⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface and secured with wheel chocks before lifting.
•Always wear safety glasses when working with tires and pressure systems.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible uneven tire wear
•Decreased fuel efficiency
•Vehicle handling issues, such as pulling to one side
•Physical inspection shows tires appear deflated

Diagnostic Steps

1
Check tire pressures using a tire pressure gauge to ensure all tires are inflated to the recommended PSI.
2
Inspect each tire for visible damage or punctures that may cause air leaks.
3
Scan the vehicle's onboard computer for any TPMS-related error codes using an OBD-II scanner.
4
Verify the TPMS sensors are functioning by checking their battery status and signal transmission.
5
Inspect the TPMS reset button, usually located under the steering column or in the glove box, to ensure it is operational.
6
Check for any recent tire changes or rotations that may have affected the TPMS.

Solution

Solution

1. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the pressure in all four tires.
2. Inflate any under-inflated tires to the manufacturer’s recommended PSI (check the driver's side door jamb for specifications).
3. If over-inflated, release some air until the correct pressure is achieved.

2. TPMS Sensor Inspection

Sub-steps:
1. Remove the tire from the wheel if there is a suspicion of sensor damage.
2. Inspect TPMS sensor for physical damage or corrosion.
3. If damaged, replace the TPMS sensor with a new one and ensure it is properly seated.
4. Reinstall the tire onto the wheel and ensure it is properly balanced.

3. TPMS Reset

Sub-steps:
1. Locate the TPMS reset button (usually under the steering column).
2. Turn the ignition to the 'ON' position without starting the engine.
3. Press and hold the TPMS reset button until the TPMS warning light blinks three times, then release it.
4. Start the vehicle and allow it to run for a few minutes to see if the light turns off.

4. Recalibration (if needed)

Sub-steps:
1. Drive the vehicle at speeds above 30 mph for about 10-15 minutes to allow the TPMS to recalibrate.
2. Monitor the tire pressure warning light to see if it stays off.

Tools Required:

Tire pressure gauge
OBD-II scanner
Tire iron
Jack and jack stands
TPMS tool (if replacing sensors)

Parts Required:

New TPMS sensors (if damaged)
Tire valve cores (if leaking)

Estimated Repair Time: 1-2 hours

Safety Warnings:

Ensure the vehicle is on a flat surface and secured with wheel chocks before lifting.
Always wear safety glasses when working with tires and pressure systems.
